A study of \({\mathrm{b}}\bar{\mathrm{b}}\) production in e+e collisions at \(\sqrt{s}=130\) –207 GeV

Abstract

Measurements are presented of R b, the ratio of the \({\mathrm{b}}\bar{\mathrm{b}}\) cross-section to the \({\mathrm{q}}\bar{\mathrm{q}}\) cross-section in e+e collisions, and the forward-backward asymmetry A FB b at twelve energy points in the range \(\sqrt{s}=130\) –207 GeV. These results are found to be consistent with the Standard Model expectations. The measurements are used to set limits on new physics scenarios involving contact interactions.
